Behavioral Biometric Player Identification

Purpose of the Study and Use of Data

You are invited to participate in a project where the aim is to investigate whether Counter-Strike 2 gameplay can be used to identify players based on behavioral biometrics (mouse movement patterns and key-press timing). For detection of cheaters and smurfing through correlating multiple accounts to the same player. Your CS2 match demos will be used to extract behavioral features and to build and evaluate identification models. Results will be used for academic purposes only (thesis, presentations, and scientific publications).

Data Handling

NTNU is responsible for the personal data processed in the project. Demos and derived data are stored securely on NTNU infrastructure in Norway. Access is restricted to the researcher and authorized NTNU staff.

Participation is voluntary

By registrating, you voluntarily provide the information necessary to automatically collect your CS2 match demos via Steam (using your latest share code, auth code, and SteamID). Only Wingman, Competitive, and Premier matches are collected. After registration, collection runs in the background without any further action required from you. There will be no negative consequences if you do not want to participate or if you later request to have your personal data deleted.

300€ Giveaway

All registered participants are automatically entered into a 300€ giveaway split between six winners (50€ skin each). Each submitted match counts as one additional entry. Winners are contacted by email; prizes are drawn on 20 December 2025 and 30 April 2026.

Purpose: Academic research for a master's thesis at NTNU analyzing behavioral biometrics in video games.
Legal basis: Processing relies on your explicit consent (GDPR Art. 6(1)(a) and Art. 9(2)(a)), which you may withdraw at any time.
Data controller: Norwegian University of Science and Technology (NTNU), with the Rector as the formal data controller.
Storage and retention: Data collection ends 30 April 2026; identifiable data are deleted by 30 June 2026. Anonymized datasets may be retained for reproducibility.
Your rights: You may request access, correction, deletion, restriction, or a copy of your data without negative consequences.
Complaints: Contact the Norwegian Data Protection Authority (Datatilsynet) if you believe your privacy rights have been violated.
